This report concerns rare ventricular malformations observed in four fetal brains. Multiple aqueductal diverticula were the only malformation of the central nervous system (CNS) in one case, unilateral diverticula of the 4th ventricle in a holoprosencephaly and a hydrocephaly, and a ventral accessory aqueduct in a fetus with trisomy 18. These findings are the pathologic progression of embryonal ventricular recesses which may be seen in normal brains.
本报告涉及在四个胎儿大脑中观察到的罕见心室畸形。在一个病例中，多个导水管憩室是中枢神经系统（CNS）的唯一畸形；在无脑儿合并脑积水病例中，第四脑室存在单侧憩室；在18三体胎儿中，存在一个腹侧副导水管。这些发现是胚胎心室隐窝的病理进展，在正常大脑中也可能出现。
